LASIK Q & A

James N. Cohn M.D. & Associates

What is Lasik?

LASIK is an outpatient surgical procedure that corrects the three most common reasons for needing assistive eyewear:

  • Nearsightedness, or myopia: only able to clearly see objects up close
  • Farsightedness, or hyperopia: only able to clearly see objects far away
  • Astigmatism: images seem blurry, regardless of distance

Lasik includes several different surgical techniques that reshape your cornea to alleviate the blurriness — known as refractive error — that necessitates corrective lenses like glasses or contacts.

How does Lasik work?

The difference between the curvature of your cornea and the length of your eye causes a refractive error (blurriness), making focusing difficult.

When Dr. Cohn corrects your eyesight with Lasik, he uses an ultraviolet laser to remove a thin layer of your corneal tissue. By thinning your cornea, it gets reshaped so that light rays focus precisely on your retina.

How is Lasik performed?

The Lasik procedure takes approximately 15 minutes and is performed while you are awake. Prior to the procedure, Dr. Cohn gives you medication to help you relax, and anesthetic eye drops to numb your eye completely.

The laser then cuts a precise ultra-thin flap on the corneal surface.  This flap is then painlessly folded back out of the way, in preparation for the custom laser wavefront treatment.

The Wavefront Scanner then makes hundreds of measurements across the front of your eye, much like pixels on a computer.  The Laser then treats each spot individually which changes the shape of your cornea in an individualized, custom manner thus, getting rid of your nearsightedness, farsightedness, and astigmatism.

The flap is then gently replaced and the procedure is repeated on the other eye.

What can I expect after surgery?

You'll heal quickly after your surgery is over, but be sure to avoid going in the water for the two weeks following surgery, or engaging in strenuous activities — like sports — for a few days (four weeks for impact sports). You may even want to take a few days off from work.

Be sure to avoid rubbing your eyes the first week following the procedure as the flap is very delicate. Prescription eye drops are used for 5 days to assure proper healing. Artificial tear drops are also used to lubricate the eyes for the first few weeks.
